I just looked up the Performance Tool W2977...it’s like $30. How was that outside of his budget? I just assumed it was because you said so. Either way my bad.
My bad for not looking up the current price of that model. They used to be a lot more expensive, $130 to $256 but the price has really dropped on them this year. I did not realize that model had come down so much. Here is a link to a mom and pop shop through Walmart who is still trying to get $200+ for them:
